Team Sky’s Geraint Thomas claimed a fine solo victory on stage two of Tirreno-Adriatico.
The Briton attacked with about 5km of the 228km stage to go and held off the chasing peleton to win by nine seconds in Pomarance, Italy.
The victory came the day after a disastrous team time trial performance by Team Sky on stage one.
However, time lost on that first stage means Welshman Thomas, 30, is highly unlikely to challenge for the title.
BMC Racing’s Greg van Avermaet of Belgium leads the general classification, followed by team-mates Rohan Dennis of Australia and American Tejay van Garderen.
Stage two result:
1. Geraint Thomas (GB/Team Sky) 5hrs 51mins 44secs
2. Tom Dumoulin (Ned/Team Sunweb) +9secs
3. Peter Sagan (Svk/Bora-Hansgrohe) same time
